  • Disturbing torques
    • External: gravitational gradients, solar pressure, magnetic, dragging etc.
    • Internal: misalignments, movements of appendages, movements of liquids, etc.
    • Secular
  • Sensors and actuators
    • Types of sensors (Earth, Sun, stellar, inertial, magnetic, GPS)
    • Types of passive actuators (rotation, gravity, magnetic, shock absorbers)
    • Types of active actuators (reaction wheels, gyros, propellers, magnetic torque rods)
